CICS and WebSphere MQ

To configure CICS to use WebSphere MQ without triggering, you simply need to define an XA resource switch module.

To configure CICS to use WebSphere MQ with triggering enabled requires that you define both an XA resource switch module and a WebSphere MQ listener.

An older method of defining a trigger, whereby you update the WebSphere MQ fields in the system initialization table (SIT), is still supported, but is now deprecated.

Micro Focus recommends that any new triggers are set up using the special listener provided, ensuring that any triggers set up using the deprecated method are removed, as this could lead to connection conflicts.
